I used a mix of crushed New Life Spectrum pellets and Aqueon flakes for my tetras. The cories get whole NLS pellets. As a treat, they will occasionally get thawed bloodworms and crushed Omega Oneshrimp pellets ( I have to crush them because I have a piggy tetra who likes to hoard food and I am afraid she will choke on a piece too big).

I've recently added blood worms to my fish diet and at first few feedings it was slow to accept, now even the smaller fish stab at it.
my angels dont eat small flake food, they like large flakes or large anything.

My blue rams they will eat anything and I mean anything other than poop, my fave. fish next to angels
All other fish so far don't care. But so far blood worms are #1 meal
